constantly run into ERR_NETWORK_CHANGED error on chrome/mac when switching between vpn and home networks. All the browsers run into this issue

Solution 1:

As bizarre as it sounds but this is the solution : disconnect your latest updated iPhone from macbook for charing or other reasons. this issue should go away. i learnt this solution the hard way. the problem was very frustrating i tried all the solutions over the internet and even learned few mac networking commands in this process. but year unplugging your phone from laptop solves this issue. Cheers. at-least that is what worked for me. i was using mac 2019 BigSur and iOS 14.5
